My logs are full of these, having to disable plugin as its crushing the server...

For what it's worth, I put a conditional around line 342 that seems to have cleared the error.

if (function_exists('is_syndicated')) :
	if (is_syndicated()) :				
		$source = get_syndication_feed_object($post->ID);

		// added check for return object
		if ( is_object($source) ) :

			//do stuff here
			
		endif;
	endif;
endif;
